View SourceParameters
- filterExpression String
-
Filter SQL expression for restriction as a composite format string - does not include WHERE.
When escaping is needed for field names, use standard ANSI quotes.
- parameters Object
- Restriction parameter values.
Remarks
Each indexed parameter, e.g., "{0}", in the composite format filterExpression
will be converted into query parameters where each of the corresponding values in the
parameters collection will be applied as IDbDataParameter
values to an executed IDbCommand query.
If needed, field names that are escaped with standard ANSI quotes in the filter expression
will be updated to reflect what is defined in the user model.
